Figure 22 Power supply section of the EVAL-M1-CTE620N3 evaluation board
The linear voltage regulator IFX1117ME V33 generates 3.3 V from 6 V power supply V
used in the inverter external overcurrent comparator circuit and overtemperature hardware protection circuit.
Both V and 3.3 V are also present on the 20 pins iMOTION™ MADK-M1 interface connector J2 to power circuitry
CC
on the control board.
